Genetic analysis of cavefish reveals more about evolution

A multi-institutional study offers additional insight into the evolutionary process by examining how albinism evolves in cavefish. Researchers, including New York University Biology Professor Richard Borowsky, examined two populations of Mexican cavefish and found that albinism in bo...

Key brain regulatory gene shows evolution in humans

...vated PDYN gene in humans, they said their finding offers an important and intriguing piece of a puzzle of the mechanism by which humans evolved from lower primates. They also said that the discovery of this first evolutionarily selected gene is likely only the beginning of a new pathway of exploring how t...

Cancer support cells may evolve, fuel tumor growth, study shows

...ltimately promote cancer growth. The new research offers what is believed to be the first evidence that mutations within cancer cells can signal surrounding tissue cells to alter their molecular composition in ways that promote tumor growth and proliferation. Moreover, the findings also suggest that cell m...

In SAD patients, autumn antidepressants can prevent winter depression

...on. Starting antidepressant treatment in the fall offers a new option for reducing the rate of fall-winter ...y opinion, the treatment used in the present study offers a valuable new option for those afflicted year after year by winter depression." ...

The secret love life of plants

...enetically dissected, the existence of this mutant offers new possibilities to learn about the development of endosperm and the embryo in seeds. In the next few months, the researchers hope above all to find out how exactly the signal functions and what chemical reactions are behind it. "Explaining the mec...

3D ultrasound device poised to advance minimally invasive surgery

...e two-dimensional ultrasound imaging now available offers surgeons only a limited view, which can impede their depth perception and make such procedures difficult to master. "Our ultrasound device could really advance the use of minimally invasive surgery," Smith said. "By allowing surgeons to essentially ...

Bones from blood: Scientists aim to break new ground on fractures

...Sociology and Philosophy in a project such as this offers the opportunity for us to explore a more ethically and socially integrated kind of biology," he added. Professor Andrew Webster and Dr Nik Brown, of the Science and Technology Studies Unit (SATSU) in the Department of Sociology, will link the scient...

"Our ultrasound device could really advance the use of minimally invasive surgery," Smith said. "By allowing surgeons to essentially ...

Carnegie Mellon develops non-invasive technique to detect transplant rejection at cellular level

...their movement to targeted sites. Our new approach offers almost unlimited potential for monitoring cell therapies, such as those using stem cells, and for tracking cellular and developmental processes," Ho said. For the research reported in PNAS, Yijen Wu, research biologist at the Pittsburgh NMR Center f...

Largest study of human 'interactome' reveals a novel way

...f proteins involved in different genetic disorders offers a novel approach for more rapidly identifying new candidate genes involved in human diseases," he says. The analysis included interactions among 1,077 genes coding for proteins linked to 3,133 diseases, the researchers report. Significantly, it sh...

Liver cancer linked to cellular repair pathway

... in immature, stem-like liver cells, the discovery offers hope for targeted treatment of liver cancer, one of the leading causes of cancer-related death in the world. Laboratory experiments show that blocking the Hedgehog pathway kills cancer cells but leaves mature healthy liver cells intact, the researche...

Rice bioengineers pioneer techniques for knee repair

...sembly technique for growing replacement cartilage offers the first hope of replacing the entire articular surface of knees damaged by arthritis. The technique, developed at Rice University's Musculoskeletal Bioengineering Laboratory, is described in this month's issue of the journal Tissue Engineering. "T...

Sexual reproduction delays aging in a mammalian species

...mechanisms that underlie aging, since this species offers the rare opportunity to study differential aging rates among individuals possessing the same genes and experiencing the same environmental conditions, apparently differing only in the aspect of pair-bonding and engaging in sexual activity. ...

Scientists discover interplay between genes and viruses in tiny ocean plankton

...ausing bacteria. In an ocean habitat, the exchange offers marine microbes a diverse palette of potential gene combinations, each of which might be best suited for a particular environment. "This would allow the overall population to persist despite complex and unpredictable environmental changes," said Chis...

GlycoFi announces the first production of antibodies with human glycosylation in yeast

...gnificantly improved. Moreover, this same approach offers the potential to improve other glycosylation-dependent drug properties (such as solubility, half-life, or tissue distribution). Given the mature and well-established nature of yeast-based protein production technology, the reported work also promises...

New research demonstrates bone-marrow derived stem cells can reverse genetic kidney disease

Powerful technique for multiplying adult stem cells may aid therapies

...iply an adult stem cell 30-fold, an expansion that offers tremendous promise for treatments such as bone marrow transplants and perhaps even gene therapy. "A 30-fold increase is ten times higher than anyone's achieved before," says Lodish, senior author on the paper, which will be published January ...

New nano-canary in the nanotoxicology coalmine: The body itself

...ell Fourier transform infrared, FTIR, spectroscopy offers several attractive features for these investigations. These include the potential to detect biologically active nanoparticles without any prior knowledge of cell signaling pathways affected by them or need of a contrast agent to detect the biologica...

Researchers release new variety of asparagus

...hers have released a new variety of asparagus that offers a higher yield than previous varieties of the vegetable and boasts an excellent spear quality, marked by a high percentage of marketable spears. Higher yield of marketable spears reduces the impact of high land and labor costs, thereby making the as...

Warbling whales speak a language all their own
